Automatic Discovery of Candidates and Members
Network Assistant forms a community using CDP to locate or discover all the available devices in the
network. Beginning with the IP address for a starting device and the port numbers for HTTP (or HTTPS)
protocols, Network Assistant uses CDP to compile a list of community candidates that neighbor the
starting device. Network Assistant can discover candidate and member devices across multiple networks
and VLANs as long as they have valid IP addresses.
By default, Network Assistant in community mode discovers up to four hops away.

An IP address has been obtained.
Cisco Discovery Protocol (CDP) version 2 is enabled (the default) (if you want the device to be
auto-discovered).
HTTP (or HTTPS) is enabled.
A cluster member can be added to a community, but the reverse is not possible.
If a cluster commander is added to a community, the other member devices of the cluster are not
added automatically. The cluster members must be added to the community on an individual
basis in order to be managed.
